In adulthood, DHT contributes to balding, prostate growth, and sebaceous gland activity. Although androgens are commonly thought of only as male sex hormones, females also have them, but at lower levels: they function in libido and sexual arousal. Androgens are the precursors to estrogens in both men and women.
Plasma levels of DHEA in adult men are 10 to 25 nM, in premenopausal women are 5 to 30 nM, and in postmenopausal women are 2 to 20 nM. [25] Conversely, DHEA-S levels are an order of magnitude higher at 1–10 μM. [25] Levels of DHEA and DHEA-S decline to the lower nanomolar and micromolar ranges in men and women aged 60 to 80 years.

Testosterone is the primary male sex hormone and androgen in males. [3] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
Cortical development of the adrenal gland is regulated mostly by ACTH, a hormone produced by the pituitary gland that stimulates cortisol synthesis. [40] During midgestation, the fetal zone occupies most of the cortical volume and produces 100–200 mg/day of DHEA-S , an androgen and precursor of both androgens and estrogens (female sex ...
androgen: adrenal glands, gonads: AR: Substrate for estrogen: Dihydrotestosterone: androgen: DHT: multiple: AR: 5-DHT or DHT is a male reproductive hormone that targets the prostate gland, bulbourethral gland, seminal vesicles, penis and scrotum and promotes growth/mitosis/cell maturation and differentiation.
A 2005 placebo-controlled study looked at men and women aged 45 to 65 with midlife-onset major or minor depression. Participants followed a six-week DHEA treatment plan that included 90 milligrams ...
Androgens that bind to and activate the androgen receptor have numerous physiological functions which can broadly divided into androgenic (male sexual development) and anabolic (building muscle and bone). The anabolic effects are important in both males and females, although females have lower circulating levels of androgens.
Hyperandrogenism is a medical condition characterized by high levels of androgens. It is more common in women than men. [4] Symptoms of hyperandrogenism may include acne, seborrhea, hair loss on the scalp, increased body or facial hair, and infrequent or absent menstruation. [1] [2] Complications may include high blood cholesterol and diabetes. [4]
